    Bases for alternative nonparametric mincer function
    (Universidad de Cuenca, 2017-01) Sacoto Molina, Matias Nicolas; Brondino, Alejandro
    This work undertakes a nonparametric regression in order to assess the viability of this technique in modeling a simplified Mincer Function of earnings applied to the NBA players’ wages. The main advantages of using this technique is that it does not rely on assumptions and the statistical inference is not sensitive to distributions disturbances due to violations of the assumptions. The results of the nonparametric estimation are compared to a classical OLS regression. We found evidence that the OLS estimator did not fulfilled the assumptions that this method requires, therefore, the statistical inference form this estimation could lead to wrong conclusions (due to lack of efficiency), unless some correction that solves the violation to the assumptions is applied to the model. On the other hand, the confidence intervals obtained from the nonparametric regression are more accurate and less sensitive to variability and magnitude of the variables. Consequently, the nonparametric estimation would be an alternative to model the behaviour of the wages avoiding strong assumptions that could lead to wrong statistical inference conclusions.

    Fuentes de la desigualdad económica en Ecuador
    (Universidad de Cuenca, 2017-01) Ramírez Alvarez, José Fernando; Díaz Sánchez, Juan
    In the last decades, the economic inequality problem has taken relevance in most economies in the world. Ecuador has been no exception. In 2014, the 5% of the richest population of Ecuador concentrated 46 times the income of 5% of the poorest population. This disparity creates a serious controversy with the development principles stipulated in the ecuadorian constitution. In this context, this paper analyzes the main income sources that contributes the economic inequality in Ecuador. The data come from the Survey of Living Conditions 2013-2014.
